Answer:
see the explanation
Step-by-step explanation:
we have that
The scale factor is
[tex]1\frac{1}{2}=1.5[/tex]
we know that
To find the length of the segment CZ, multiply the segment CR by the scale factor
so
[tex]CZ=CR(1.5)[/tex]
substitute
[tex]CZ=4(1.5)=6\ units[/tex]
therefore
Roy's diagram is not correct, because on the graph, Roy draws the length of the CZ segment equal to 10 units instead of 6 units.
Roy is using a scale factor equal to 2.5 instead of 1.5.
